having a defeatist attitude will not serve you well in terms of forming groups in classic. learn how to talk to people, or maybe play a class that is capable of more than one thing so you have some flexibility in forming groups. assuming you're a rogue like fragmatikz said, you're boned because you're fighting a bunch of other classes for gear so no one will want to group with you unless you have a reputation as an excellent rogue or you're willing to make some comprimises. that's life, you picked a selfish class so people will give you that back in return. my advice is: spend your time farming/doing something else while looking to fill out a group
